Abstract A novel combined machining approach combining short electric arc machining and electrochemical machining (SEAM-ECM) is proposed in this study. It aims to improve the surface integrity of TC4 titanium alloy by adding compressed air and electrolyte into the SEAM. This approach can change the material removal mechanism of the conventional SEAM and improve the gap flow field distribution and discharge state using the dual fluid properties of electrolyte and air mixed medium. The effects of gas addition on the state of the gap flow field and the electrical conductivity of the mixed medium are illustrated by flow field simulation. The effects of the presence or absence of air and the electrical conductivity of the solution on the machining performance are compared by experiments. The results show that the recast layer is weakened by using electrolyte and air mixed medium in SEAM-ECM compared to SEAM alone. The addition of high-speed air reduces defects such as melt drops, particles, holes. It performs with higher precision and finishes than ECM alone, the overall surface integrity has been significantly improved.
